“…This problem has many applications in, e.g., machine learning [4,3], scheduling [74,44], and game theory [36,28,26]. Moreover, important special cases of this problem are the RAP with box constraints (see [61]), the RAP with generalized bound constraints (see [69]), and the RAP with nested constraints (see [82]). Important application areas for in particular these special cases include, among many others, regularized learning [12,47], telecommunications and energy management [60,79,88], and statistics [57,15] (see also the overviews in [61] and [82]).…”
